摘要
本文针对重庆市某沟埋式市政混凝土箱涵的开裂事件 ,运用了弹性地基梁理论进行箱涵结构计算。基于弹性地基箱梁的分析模型 ,简化为简支箱梁问题 ,计算了箱梁内力 ,据此进行了箱涵正截面尺寸、弯曲强度及裂缝验算。理论上证实了箱涵开裂的必然性。也证实了本文分析方法的可靠性。
The cracking in embedded concrete box culvert in Chongqing City was studied and the structural calculation checks in this paper were performed using elastic foundation beam theory. The cross section, bending strength and crack of the culvert were checked. Results show the inevitability for cracking of the box culvert and reliability of this analysis method.
